For most Lexus models, there’s a button above your ankle for the TPMS, it faces the floor mat. Just press it for 4 secs & that will reset the sensor. I reset mine earlier today (cold here) & it’s still off.
MY 2008 GX470 DOS NOT HAVE GREEN MODULE AND BLUE WIRE IS THE SECOND INSTEAD OF THIRD LIKE YOU HAVE. SO, YOUR TECHNIQUE DOES NOT WORK ON 2008 LEXUS GX470
